MAGAZINE-RIFLE.

Specification of Letters Patent.

Patented June 4, 1907.

Application filed April 19,1906. Serial No. 312,545.

To /tZZ rui/1.0m, it Wawy concern.-

Be it known that l, Josnr LAUBER, a subject of the Emperor of Austria,and residing at No. l Laxenburgerstrasse, Vienna, Ausi tria, haveinvented new and useful lmprovei ments in Magazine-Rifles, of which thefollowing is a full, clear, and exact description.

The present invention relates to that class of riiies in which thecartridge is introduced laterally into the barrel in front of the breechblock, then pushed forward by the l latter into the breech, locked andfired by releasing the firing pin and the object of the invention is toeffect the forward movement of the breech block and locking of the sameby means of the pull of the trigger. Thus the first part of the pull ofthe trigger will force the breech block forward, thrust the cartridgehome in the breech and lock the block in position, after which by thefurther movement of the trigger an auxiliary trigger will be operatedand thus release the firing pinto discharge the cartridge.

ln order to render the present specification easily intelligiblereference is had to the accompanying` drawing in which similar numeralsof reference denote similar parts throughout the several viewsz# Figure1 is a part longitudinal section throughv the breech block and triggermechanism of a rifle carried out according to the present invention,showing the position of the parts at the moment of firing. Fig. 2 is asimilar part section showing the position of the parts after the triggerhas been released. Fig. 3 is a similar section showing a modified formof the invention with the parts in a similar position to that occupiedby them in Fig. 1. Fig. 4 is a similar section of the modification ofFig. 3 with the parts corresponding in position to those of Fig. 2. Fig.5 is a plan view of a detail and Fig. 6 a cross section through themagazine.

Referring first to Figs. 1, 2, 5 and breech block and trigger mechanismhousing consists of the upper and lower walls 2 and 3, the rear wall 4and a horizontal partition wall 6 dividing the said housing into theupper breech block casing to the front end of which the barrel 1 isattached having the cartridge seating or breech 5, while the triggermechanism is mounted in the lower chamber.

lt may here be stated that the magazine (Fig. 6) is of knownconstruction consisting of the two walls 53, 54 having the feed 6 r-Thesprings 52 for forcing the cartridge laterally into the breech as willbe readily understood. Both the cartridge feed as also the extractingand ejecting mechanism may be of any suitable known construction. Thecartridge 33 is fed laterally to the breech in front of the l breechblock and is forced home by the latter, but the movement of the breechblock to perform this operation is derived from the trigger mechanism.The trigger 12 is mounted on a stationary pivot 10 and has rigidlyconnected thereto a tooth segment 11 which engages with a segment 9rigidly connected to one arm of a lazy tongs 7. The rear end of thetongs is fast on the pivot 8 to which the segment 9 is attached and whenthe trigger is pulled back the lazy tongs will be stretched outforwardly. The front end of the lazy tongs is linked to an arm 14 madein one piece with, or rigidly attached to the breech block 15 andextending downwardly through and guided in a slot of the wall 6. Thebreech block 15 carries within it the firing pin the shaft 17 of whichextends out through a boring in the rear closing screw head 16 andcarries outside the block the downwardly extending lug 1S.

Mounted on a stationary pivot 22 at the rear of the trigger 12, is thefiring trigger 23, having an upwardly extending arm 25 adapted tocoperate with the firing pin detent lever 26, 27 mounted on a stationarypivot and having its nose 27 extending into the path of movement of thelug 18 of the firing pin. This detent lever is normally held against astop by means of a spring 28 and when the firing lever is pressedbackward by means of the button 24 on the lower rear side of the trigger12, it forces the detent lever to the position shown in Fig. 1, fromunder the lug 1S and releases the firing pin to discharge the cartridgeunder the action of the main spring 19. As soon as the trigger 12 hasbeen released the spring 29 returns the breech block and all the partsto their position of rest as indicated at Fig. 2. The backward movementof the main trigger 12 is limited by a spring stop 21 having two camshaped projections between which the part 12 of the trigger engages whenit has reached its backward limit of ull. On releasing the trigger thespring 29 will pull the trigger free of the spring stop owing to thestrength of the former and the elasticity of the latter.

The breechblock is locked in its forward position while the cartridge isbeing fired by IOO the following mechanism: Pivoted to a stationarypivot 44 is a bell crank lever, 45 46, the longer arm 45 of whichoperates two vertically movable locking bolts`47 and 48 I which arenormally held away from the breech block 15 by means of their respectivesprings 49 and 50. These bolts pass upwardly through the wall 6 and therear one 47 which has an inclined rear surface enl gages behind adownwardly projecting catch I 42 on the breech block, which catch movesin a horizontal slot 5l of the upper part of the wall 6, while the bolt48 engages in a recess 43 of the breech block, both engagel ments takingplace when the block is in its forward position. This is effected in thel following mannerz-The shorter arm 46 of the bell crank lever lies inthe path of movement of the arm 14 of the breech block and as the latterreaches the end of its forward stroke, it strikes the short end 46 ofthe bell crank lever raising the arm 45 and forcing the two lockingbolts 47 and 48 into engagement with their respective parts of thebreech block thus securing it against backward movement while thecartridge is being fired. On releasing the trigger the bolts 47 and 48are withdrawn by their springs 49 and 50 and the breech block isreturned to its initial position while the next cartridge is being fedto the breech. The rear end of the breech bolt chamber is closed by ascrew 30.

Instead of the lazy tongs of Figs. 1 and 2 the lever arrangement ofFigs. 3 and 4 may be employed. This arrangement consists of a lever 40mounted on a stationary pivot 39 of the housing and having a slot 38 inwhich a pin 37 engages mounted on the end of an upper prolongation 36 ofthe trigger 12. The lower end of the lever 40 is linked to a lever 41which is linked in its turn to the breech block 15. In this case thespring 29 I is attached to the upwardly extending arm 36 of the trigger12. Thus as will be readily understood on reference to Figs. 3 and 4,when the trigger is pulled back the levers 40 and 41 will force thebreech block forward, when the same will be locked in its forwardposition by means of the contact of the lever arm 41 with the short arm46 of the bell crank lever 45, 46 in a similar manner to that describedwith reference to Fig. l.

The operation of the device which will be readily understood from theforegoing description takes place, brieiiy described in the followingmanner:*VVhile the cartridge 33 is being fed to the breach the parts arein the position sh own in Fig. 2. As soon as the trigger is pulledbackward the lazy tongs 7 of Figs.

1 and 2 or the levers 40 and 41 of Figs. 3 and 4 tongs connection fromsaid arm to the are immediately extended forcing the breech block 15forward and pushing the cartrid e home. As the breech block advances itwill carry the firing pin with it until the stop 27 arrests the lug 18,after which the block will advance alone the firing pin being held backagainst the pressure or tension of the main spring. On continuing thebackward pull of the trigger the cartridge will be forced home in thebreech and the locking bolts 47, 48 will be forced up into engagementwith the locking devices of the breech block, by the arm 14 operatingthe bell crank lever 45, 46'

so that the breech block will be securely locked in its operativeposition forward. The further pull back of the trigger 12 will cause thebutton 24 to push thertrigger 23 backward, thus upsetting the tumbler ordetent 27 against the 'action of its spring and releasing the iirin pinwhich flies forward under the action o the main spring and fires thecartridge. As soon as the trigger 12 is released the parts are returnedto their initial position by the action ofthe spring 29.

The details ofvconstruction might be varied in a great many ways withoutdeparting from the spirit of the invention.

I claim as my invention 1. In a magazine fire-arm having lateralcartridge feed .trigger mechanism and a sliding breech block, thecombination of an arm on the breech block extending into the casingcontaining the trigger mechanism, a lazy trigger mechanism and a springto return the parts to their initial position after the trigger has beenreleased.

2. In a magazine fire-arm having lateral cartridge feed, a triggermechanism and sliding breech block, the combination of means for forcingthe breech block forward when the trigger is pulled back, means forarresting the firing pin before the breech block has attained itsforward position, means for looking the breech block in its forwardposition consisting of vertically movable bolts springs to normallyretain them out of engagement, and a bell crank lever operated by theforward movement of the block to force said bolts up to engage thebreech block and lock the same, means for releasing the firing pin whenthe breech block has been locked and means for returning the parts totheir initial position as soon as the trigger has been released.

In testimony whereof I affix my signature in the presence of twowitnesses.
